Why? “Different type of atoms” which refers to different element present in the compound. Only Barium, Oxygen, and Hydrogen found in that compound, thus there are 3 types of atom founded it hydrated barium hydroxide.
I hope this enlighten. Apologize for any English or Chemistry concepts.
Thank you for posting your question here at brainly. Below is the solution:
<span>moles HClO4 = 0.100 L x 0.18 M = 0.018 moles LiOH = 0.030 L x 0.27 = 0.0081 moles H+ in excess = 0.018 - 0.0081 = 0.0099 total volume = 0.130 L [H+] = 0.0099/ 0.130= 0.0762 M pH = 1.12</span>
